inattention
UK: ˌɪnəˈtɛnʃən | US: ˌɪnəˈtɛnʃən
n. lack of attention or concentration; neglect or disregard.
The word "inattention" combines the Latin-derived prefix "in-" (meaning "not") with the noun "attention," which originates from the Latin "attendere" (to stretch toward, focus on). The prefix negates the root, creating a term that literally means "not focusing." Over time, it evolved to describe a state of distraction or neglect, reflecting the logical progression from physical focus (e.g., turning one's head) to mental concentration.
